ATI Pharmacology Proctored Exam 2023 Quizlet
1. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
- A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
- B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
- C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
- D. To lower blood glucose by stimulating the release of insulin
Correct answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.
2. A client has a new prescription for Hydrochlorothiazide. Which of the following adverse effects should the nurse monitor?
- A. Hyponatremia
- B. Hyperkalemia
- C. Hypercalcemia
- D. Hypoglycemia
Correct answer: A
Rationale: Corrected Rationale: Hydrochlorothiazide, a diuretic, can lead to electrolyte imbalances, particularly hyponatremia (low sodium levels). The nurse should closely monitor the client's sodium levels due to the potential adverse effect of Hydrochlorothiazide. Incorrect Rationales: - Hyperkalemia (Choice B) is less likely to be caused by Hydrochlorothiazide; in fact, it can lead to hypokalemia. - Hypercalcemia (Choice C) is not a common adverse effect of Hydrochlorothiazide. - Hypoglycemia (Choice D) is not directly associated with Hydrochlorothiazide use.
3. A client with increased intracranial pressure is receiving Mannitol. Which finding should the nurse report to the provider?
- A. Blood glucose 150 mg/dL
- B. Urine output 40 mL/hr
- C. Dyspnea
- D. Bilateral equal pupil size
Correct answer: C
Rationale: Dyspnea is a concerning finding in a client receiving Mannitol as it can be a manifestation of heart failure, an adverse effect of the medication. It suggests potential fluid overload or exacerbation of heart conditions, both of which require immediate attention. Reporting dyspnea promptly allows for timely evaluation and management. Blood glucose levels and urine output are important parameters to monitor but are not directly related to the administration of Mannitol for increased intracranial pressure. Bilateral equal pupil size is a normal and expected finding.
4. A client receives a local anesthetic of Lidocaine during the repair of a skin laceration. For which of the following adverse reactions should the nurse monitor the client?
- A. Seizures
- B. Tachycardia
- C. Hypertension
- D. Fever
Correct answer: A
Rationale: Seizures are a potential adverse reaction to local anesthetics like Lidocaine. Lidocaine can affect the central nervous system and, in some cases, lead to seizure activity. Therefore, it is important for the nurse to monitor the client for any signs of seizures during and after the administration of Lidocaine.
5. A client is starting a new prescription for enalapril. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Rise slowly from a sitting position.
- C. Avoid salt substitutes.
- D. Avoid exposure to sunlight.
Correct answer: C
Rationale: The correct instruction for a client starting enalapril is to avoid salt substitutes. Salt substitutes may contain potassium, which could lead to elevated potassium levels when combined with enalapril, increasing the risk of hyperkalemia. Choices A, B, and D are incorrect because there is no specific need to take enalapril with food, rise slowly from a sitting position, or avoid exposure to sunlight when taking this medication.
